Trezor Bridge is a communication service that allows Trezor hardware wallets to securely interact with web browsers and decentralized applications without exposing private keys.
Trezor Bridge is a lightweight software component that enables secure communication between Trezor hardware devices and supported web applications.
It acts as a secure link, allowing browsers to detect the hardware wallet while ensuring that sensitive cryptographic operations remain inside the Trezor device.
Web-based wallets and blockchain services require a reliable method to interact with hardware wallets. Trezor Bridge fulfills this role by facilitating communication while maintaining strict security boundaries.
Allows web apps to detect and communicate with Trezor devices.
Prevents direct access to private keys from the browser environment.
Enables transaction signing only after physical device confirmation.
Works across multiple operating systems and modern browsers.
Trezor Bridge runs as a background service on your computer. When a browser requests access to the Trezor device, Bridge relays messages securely between the browser and hardware wallet.
All cryptographic signing and verification processes occur on the Trezor device, ensuring private keys never leave the hardware.
Trezor Bridge is primarily required when interacting with web-based wallet interfaces or decentralized applications that do not support native device communication.
After installation, Trezor Bridge runs silently in the background.
Trezor Bridge is designed to minimize attack surfaces by acting only as a communication layer, not a wallet or key storage solution.
Trezor Suite is a full wallet management application, while Trezor Bridge serves as a connectivity tool for browsers.
Users who primarily use Trezor Suite may not require Trezor Bridge, as Suite includes built-in communication features.
If your browser cannot detect your Trezor device, Trezor Bridge may not be running or properly installed.
Trezor Bridge plays a vital role in enabling secure communication between Trezor hardware wallets and web-based blockchain applications.
By acting as a safe intermediary, it ensures users can interact with decentralized services without compromising private key security.
